A user-specific, electroencephalogram data-based secure encryption generator maps artificial neural network neuron elements to electroencephalogram data signals generated from scanning neural activity of a user while the user executes a mental activity. weighting factors are trained to transform the electroencephalogram data signals into a first set of weighted signals that are different from weighted signals generated from scanning neural activity of the user while the user executes another, different activity, and from weighted signals generated from scanning neural activity of another user while executing a similar mental activity. The trained weighting factors are associated with the first set of electroencephalogram data signals and the current mental activity. Thus, a reproducible electroencephalogram encryption key is defined that is unique to the user as a function of one or both of the trained weighting factors and the first weighted set of electroencephalogram data signals.

Cryptography and cryptology refer to encryption methods, systems and techniques for transmitting secure information communications that prevent the disclosure, loss or theft of confidential, non-public text or data information within transmitted information to unauthorized receivers of the information. Encryption is the process of encoding messages or information components thereof in such a way that only authorized senders or receivers or other persons can decode and thereby access the encoded information, which may include text messages and data in a variety of formatted or raw forms. Encryption does not of itself prevent interception of a transmitted message by unauthorized receivers, but instead denies access to encoded content information within the message to the unauthorized receiver.

In an encryption scheme, secure communication information is generally encrypted using an encryption algorithm as a function of an encryption key, to generate encoded information that may be transmitted without fear of loss of the secure information within the message as the encoded message may only be read if decrypted in a subsequent encryption algorithm step or process that uses the same key or other appropriate decryption key. An authorized recipient can easily decrypt the message by application of the decryption key, wherein interceptors or other unauthorized receivers are denied access to the secure data within the encoded message without the decryption key.

Encryption methods include symmetric key encryption and public key encryption. In symmetric key encryption, the encryption and decryption keys are the same, and senders and authorized receivers use the same key in order to encode and decode the message, respectively. Accordingly the symmetric key must be kept confidential and secure from any other unauthorized receivers in order to prevent decoding and loss of confidentiality and security of the encrypted message information content.

Public key encryption uses public and private key pairs for encryption and decryption, wherein an authorized receiver uses a cryptographic algorithm to generate their own private key from a public key and then uses their private key to decode encoded messages. Unlike symmetric key, public key encryption does not require a secure channel for an initial exchange of secret keys between the parties, and the public key may be published without compromising security. Strength of security instead depends instead on the impossibility, or computational impracticality, of an unauthorized receiver determining a properly generated private key from the corresponding public key.

Cryptographic algorithms used to generate public key are generally based on mathematical problems that admit no efficient solution, for example those inherent in certain integer factorizations, discrete logarithms, elliptic curve relationships, etc.

In one aspect of the present invention, a method for a secure encryption generator based on user-specific electroencephalogram data includes mapping artificial neural network neuron elements to a first set of electroencephalogram data signals generated from scanning neural activity of a user while the user executes a current mental activity. A first set of artificial neural network neuron element weighting factors are trained to transform the first set of electroencephalogram data signals into a weighted set of electroencephalogram data signals that are different from a weighted set of electroencephalogram data signals generated from scanning neural activity of the user while executing another, different activity, and from a weighted set of electroencephalogram data signals generated from scanning neural activity of another user while executing a similar mental activity. The trained set of artificial neural network neuron element weighting factors is associated with the first set of electroencephalogram data signals and the current mental activity. Thus, a reproducible electroencephalogram encryption key is defined that is unique to the user as a function of one or both of the trained set of artificial neural network neuron element weighting factors and the first weighted set of electroencephalogram data signals.

In another aspect, a system has a hardware processor in circuit communication with a computer readable memory and a computer-readable storage medium having program instructions stored thereon. The processor executes the program instructions stored on the computer-readable storage medium via the computer readable memory and thereby maps artificial neural network neuron elements to a first set of electroencephalogram data signals generated from scanning neural activity of a user while the user executes a current mental activity. A first set of artificial neural network neuron element weighting factors are trained to transform the first set of electroencephalogram data signals into a weighted set of electroencephalogram data signals that are different from weighted set of electroencephalogram data signals generated from scanning neural activity of the user while the user executes another, different activity, and from a weighted set of electroencephalogram data signals generated from scanning neural activity of another user while executing a similar mental activity. The trained set of artificial neural network neuron element weighting factors is associated with the first set of electroencephalogram data signals and the current mental activity. Thus, a reproducible electroencephalogram encryption key is defined that is unique to the user as a function of one or both of the trained set of artificial neural network neuron element weighting factors and the first weighted set of electroencephalogram data signals.

In another aspect, a computer program product for a user-specific, electroencephalogram data-based secure encryption generator has a computer-readable storage medium with computer readable program code embodied therewith. The computer readable hardware medium is not a transitory signal per se. The computer readable program code includes instructions for execution which cause the processor to map artificial neural network neuron elements to a first set of electroencephalogram data signals generated from scanning neural activity of a user while the user executes a current mental activity. A first set of artificial neural network neuron element weighting factors are trained to transform the first set of electroencephalogram data signals into a weighted set of electroencephalogram data signals that are different from weighted set of electroencephalogram data signals generated from scanning neural activity of the user while the user executes another, different activity, and from a weighted set of electroencephalogram data signals generated from scanning neural activity of another user while executing a similar mental activity. The trained set of artificial neural network neuron element weighting factors is associated with the first set of electroencephalogram data signals and the current mental activity. Thus, a reproducible electroencephalogram encryption key is defined that is unique to the user as a function of one or both of the trained set of artificial neural network neuron element weighting factors and the first weighted set of electroencephalogram data signals.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Referring now to FIG. 1, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 comprises one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 1 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.

The computer system/server 12 is shown in the form of a general-purpose computing device. The components of computer system/server 12 may include, but are not limited to, one or more processors or processing units 16, a system memory 28, and a bus 18 that couples various system components including system memory 28 to processor 16.

Bus 18 represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnects (PCI) bus.

Computer system/server 12 typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system/server 12, and it includes both volatile and non-volatile media, removable and non-removable media.

System memory 28 can include computer system readable media in the form of volatile memory, such as random access memory (RAM) 30 and/or cache memory 32. Computer system/server 12 may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system 34 can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus 18 by one or more data media interfaces. As will be further depicted and described below, memory 28 may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention.

Program/utility 40, having a set (at least one) of program modules 42, may be stored in memory 28 by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules 42 generally carry out the functions and/or methodologies of embodiments of the invention as described herein.

Computer system/server 12 may also communicate with one or more external devices 14 such as a keyboard, a pointing device, a display 24, etc.; one or more devices that enable a user to interact with computer system/server 12; and/or any devices (e.g., network card, modem, etc.) that enable computer system/server 12 to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interfaces 22. Still yet, computer system/server 12 can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter 20. As depicted, network adapter 20 communicates with the other components of computer system/server 12 via bus 18. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system/server 12. Examples, include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.

In a public key cryptographic system, a first unique user (for example, User A or “Alice”) has a public encryption key (EA) and a second unique user (for example, User B or “Bob”) has a public encryption key (EB) that are that are generally available to each other. Alice may send a secure and encrypted message to Bob by obtaining Bob's public encryption key (EB) and using it to encrypt original message content (“M”) into an encrypted message, which may be denoted as “EB(M)”. Bob may use his private decryption key (“DB”) to decrypt the encrypted message, which may be denoted as the expression “DB(EB(M)=M.” While the respective decryption and encryption processes may be easy to compute by an unauthorized person who intercepts or otherwise acquires the encrypted message, security of the message relies on the fact that it is computationally impractical for the unauthorized person to derive the decryption key (DB) from the encryption key (EB).

An electronic signature process may also be used to enhance security in confidential communications, wherein a unique signature is used as a secure method of proof of identity for a receiver of an encrypted message (for example, User A or “Alice”) that a received message was sent by an expected sender (for example, User B or “Bob”), which may be denoted by the expression “EB (DB (M)=M,” which signifies using a decryption key (DB) for encryption and an encryption key (EB) for decryption of message content “M.” If Bob wants to send a signed message “M” to Alice, Bob may sign the message with an unique signature “S” that is determined as a function of his private decryption key (“DB”), which may be denoted as “S=DB(M).” Bob then encrypts a signature/message pair using Alice's public encryption key (EA) for transmission to Alice, which may be denoted as “EA (S).” For decryption Alice uses her private decryption key to generate S, according to “S=DA (S),” and to obtain the message content Alice uses Bob's public encryption key (EB), which may be denoted as “M=EB (S).” Alice may thereby receive Bob's message content (M) and his signature (S).

Electronic signature and public key cryptographic systems and processes present certain inadequacies. While technically very difficult, it is not impossible to derive an alphanumeric private decryption key (or an alphanumeric input used to generate the key) from a publicly available encryption key. Further, if security is not maintained and an unauthorized person acquires a private decryption key (for example, by fraud), it is possible for the unauthorized person to sign messages under the false pretense that they are an authorized person, as well as decrypt messages not intended for the unauthorized person.

Aspects of the present invention provide systems and method for generating encryption keys and signatures from personalized weighting factors that are derived from and applicable to electroencephalogram (“EEG”) data that is unique to an individual sender or receiver of secure messages. Electroencephalography is a medical technique that reads scalp electrical activity generated by brain structures. When brain cells (neurons) are activated, local current flows are produced. The EEG comprises electrical activity of an alternating type recorded from detection from the scalp surface by metal electrodes and other conductive media.

EEG data is generated by measuring voltages on the scalp generated by brain activities. EEG data generated by brain activity patterns may form wave shapes that are commonly sinusoidal and when measured from peak to peak and normally range from 0.5 to 100 μV in amplitude.

By means of Fourier transform or other processes, power spectrums from the raw EEG signals may be derived. In the derived power spectrum contributions of sine waves with different frequencies are visible. Although the spectrum is continuous, ranging from zero Hertz (Hz) up to one half of sampling frequency, the brain state of an individual may make certain frequencies more dominant. EEG power spectrum data is commonly differentiated into four basic different groups of brain waves that are distinguished by different ranges of frequency values: beta wave signals that have a frequency of greater than 13 Hz, alpha waves signals that have a frequency ranging from 8 Hz to 13 Hz, theta waves signals that have a frequency ranging from 4 Hz to 8 Hz, and delta waves signals that having a frequency of from about 0.5 Hz to 4 Hz

EEG data has attributes that are unique to the physiology of the individual user, and aspects for the present invention focus on the differences between personal EEG data sets to define unique weighting sets for individual users that are not transferrable or replicable between different users.

Further, evoked potentials or event-related potentials (ERPs) are significant voltage fluctuations resulting from evoked neural activity. An evoked potential may be initiated by an external or internal stimulus. Mental operations, such as those involved in perception, selective attention, language processing, and memory, proceed over time ranges in the order of tens of milliseconds. ERPs can help in defining the time course of these activations. Amplitudes of ERP components are often much smaller than spontaneous EEG components and thereby not readily recognizable within EEG trace data. They may be extracted from sets of EEG data recordings by digital averaging of epochs (recording periods) of EEG time-locked to repeated occurrences of sensory, cognitive, or motor events. Spontaneous background EEG fluctuations, which are random relative to time points when the stimuli occurred, may be averaged out, leaving event-related brain potentials. The remaining electrical signals reflect only that activity which is consistently associated with the stimulus processing in a time-locked way. The ERP thus reflects, with high temporal resolution, the patterns of neuronal activity evoked by a stimulus.

A brain computer interface (BCI) is a communication system that recognizes a user's command from EEG or ERP brainwave data generated by thinking of the command or executing a physical movement associated with the command. The EEG or ERP brainwave data associated with a mental command activity may be distinguished from data for other commands or activities, for example by identifying unique brain region activity combinations, or EEG or ERP profiles that are defined by subsets or portions of one or more of the beta, alpha, theta or delta wave signals that differ from the profile of a different activity.

Prior art BCI techniques focus on comparing EEG or ERP brainwave data of multiple people to identify gross or large-scale similarities that are associated with the mental activities of two or more people thinking of the same command, for example “move eyes left”, so that a common command may be recognized from the EEG data attributes of different people. In contrast, aspects of the present invention focus on determining weightings for components or attribute of EEG or ERP data that both enable replication in association with a common mental activity (command, thought, etc.), and are unique to the individual person, like a unique fingerprint. Thus, the EEG data of one person thinking of a same command as another person will have a different weighted EEG data relative to the other person, independent of any gross similarities in their raw EEG data. This will prevent the EEG data of the other person from being used in the stead of the weighted EEG data of the first person.

FIG. 4 illustrates a computer implemented (method or process) of an aspect of the present invention wherein a processor (for example, a central processing unit (CPU)) that executes code (such as code installed on a storage device in communication with the processor) that is in circuit communication with an EEG interface trains an “artificial neural network” (ANN) weighting model for a user that is used to generate a signature or private encryption key for the user from EEG signal inputs generated by neural activity of a user.

At 102 the processor establishes a circuit communication with an EEG interface that acquires current (first) EEG data signal inputs generated by scanning current neural activities of a user.

At 104 ANN model neuron elements are mapped to a current (first) set of EEG data signals generated from scanning current neural activity of the user while (during a time period that) the user executes a current distinct and identifiable mental activity.

At 106 a current (first) set of ANN model weighting factors (or weighting) are learned (trained or generated) to represent or transform the current set of EEG signals into a weighted set of EEG activity signals that are distinguishable from at least one other (second) set weighted of EEG activity signals that are generated when the user is executing a different mental activity by the user, and from another (third) weighted set of electroencephalogram data signals that are generated from scanning neural activity of another user while the user executes a mental activity that is the same, similar or analogous to current mental activity.

The weighted ANN model thus comprises a plurality of “neuron” weighting elements that may be described as exchanging messages between each other via numerically weighted decision connections that are tuned (weighted) to correspond to the neural processes of the user represented by EEG data. The other activities by the same user may be a baseline rest state, representing a null activity or “zero” value, wherein the current activity is a positive activity having value of “one”, or any other neural activity by the user that is different and distinguishable from the activity used to generate the first set of EEG signal data.

The ANN model weight set is trained into a (first) learned set of weighting factors at 106 by setting the weightings to correspond to EEG data (which may include ERP data) profile patterns that are distinguished and replicated within the user's EEG data when the user goes through repetitive iterations of an associated mental activity (particular muscle movement, image or command visualization, etc.). Training the weighting factors causes them to correspond to EEG data profile pattern distinguished and replicated within the user's EEG data when the user goes through repetitive iterations of associated mental activity.

In some aspects, the training at 106 of the learned ANN model weights further defines a learned model profile or relationship of the weights relative to each other that corresponds to values of the user's EEG data that are unique and personal to the user, essentially like an EEG fingerprint that is unique to the user supplying the current EEG data. By conforming a profile of the weightings to an EEG data profile that is unique to the user, security is enhanced: the weightings may not be replicated by another person, since they will have different and distinguishable personal EEG data.

A variety of different process may be practiced in measuring or representing the EEG signal data and in defining their associated weights at 106 in order to distinguish EEG signal data generated by different mental activities, and to thereby generate a complex and unique weighting set. Generally EEG signals are very low frequency signals, which are readily modulated into a higher digital carrier frequency for transmission or processing. Illustrative but not exhaustive examples of EEG signal processing according to the present invention include frequency or amplitude measurements, filtering, Fourier spectrum transformations and analysis, and still other options will be appreciated by one skilled in the art.

A variety of components and attributes of the EEG signal data may be mapped to the ANN weighting elements at 104 to amplify certain attributes of the EEG signal set data into a unique EEG data representation that is distinguished from other EEG data inputs. In one example a subset of one or more of the four different basic wave types (beta, alpha, theta and delta) is selected and weighted in response to determining that the selected EEG signals are sufficient to distinguish the EEG signal set from the sets generated from other mental activities.

The reproducibility of the weighted current (first) set of EEG activity signals is iteratively tested at 108, by prompting the user to repeat the current activity and again generate the EEG signals mapped to the ANN elements at 104 and weighted by the learned weights at 106 until a number of weighted transformations of the EEG data obtained from each iteration match with a threshold degree of similarity and frequency (for example, over 50%, 66.7%, 75%, 90% of three or more repetitions). In some aspects the assessment directly informs the user supplying the current EEG signals (for example, visually via a graphical user interface (GUI) display device, and/or acoustically through audio instructions), in a real-time feedback process, as to whether the current EEG signals have a sufficient reproducibility and distinctiveness qualities to be used in combination with other, different and distinct weighted EEG signal sets provided by the user to generate a valid personal signature.

Upon verification at 108 that generation of the weighted signals is repeatable by the user, at 110 the uniqueness of the ANN weight set is verified. For example, the weighting values must be computationally complex enough that they cannot be replicated by another. If not, then the weights are relearned (retrained) in additional iterations at 106. The testing processes at 108 and 110 confirms that the EEG activity signals associated with the activity may be replicated by the person (first user) for each repetition, and that the learned weightings are sufficiently unique to be secure from discovery and use by another person.

At 112 the current (first) learned set of weighting factors that are verified as repeatable at 108 and sufficiently unique at 110 are associated with the current (first) set of EEG signals and with the current distinct, reproducible and identifiable mental activity that was performed by the user to generate the current set of EEG signals.

A single ANN weight set may be used to define a reproducible EEG encryption key or electronic signature that is unique to the user, though some aspects use combinations or patterns of multiple, different ANN weight sets that are each associated with a different activity to define the reproducible EEG encryption key or electronic signature. Thus, the present example includes an optional step at 114 that determines whether a threshold number of different reproducible and identifiable mental activities of the user are identified and associated with their own distinct sets of ANN weights trained for their respective EEG data sets. For example, the threshold number may be at least two to define a binary set of different user identified mental activities that may be combined into sequences or even Boolean combination values, wherein the user may generate a pair of different EEG signal outputs from two distinct activities that signify at least different binary inputs, for example “yes” or “no”, “one” or “zero”, etc.

If determined that the threshold number is not yet generated at 114, the “current” user mental activity is replaced with a new, different (“revised current”) mental activity at 115 and the process returns to 104, wherein the revised current activity is used to generate another set of EEG data and associated weight sets via the processes at 104-106-108-110-112 to generate another set of EEG signals that are reproducible in weighted form as a function of the user's ANN weight set. This process iteratively repeats until the threshold number is met at 114, wherein the process ends by generating at 116 a reproducible EEG encryption key or electronic signature from at least one of the trained ANN weight sets.

Different activities that generate different respective EEG signal sets at 104 that may be replicable as weighted by the trained ANN model weights may be defined at a variety of granularities. For example, different respective activities used to generate weighted sets of EEG appropriate for defining personal signature signals may include EEG signal generated in response to directing muscle movements or the absence thereof, such as user eyeball movements, specific hand movements and patterns (such as to trace out or write an alphanumeric character), and other sequential combinations of a variety of different movements, as well as signals generated from “no activity” or “pauses” in movement wherein the user holds him or herself still and makes no volitional muscle movements for a “pause” period of time. The different respective activities may also include different mental thoughts, exercises or processes, including memorizing or recalling a specific image or picture, different alpha-numeric characters.

Thus, aspects of the present invention use ANN model estimates or approximations of neural functions of the user that are represented by the EEG inputs as a system (“net”) of interconnected components (“neurons”) that exchange messages between each other and have numeric weights that are tuned to generate a unique set of weight values that function as a unique signature or encryption key for the user, wherein only the EEG signal data of the user will be transformed into the expected, reproducible values.

FIG. 5 is a graphic illustration of an embodiment of the present invention wherein the personalized weighting factors (“wnA”) 302 of a sender (“Alice”) 304 and the personalized weighting factors (“wnB”) 306 of a receiver (“Bob”) 308 (as determined at 106 of FIG. 4) are made publicly available with their respective public encryption keys (“EA”) 303 and (“EB”) 307. A personal EEG signature signal 310 of the sender 304 is encrypted with the receiver's public encryption key (“EB”) 307 and sent to the receiver, wherein the personal EEG signature signal 310 is verified by the receiver using the publicly available personalized weighting factors of the sender “wnA302 as generated by an ANN model according to the embodiment of FIG. 4.

FIG. 6 illustrates an alternative embodiment of the present invention wherein at 402 a personal EEG signature is defined for a sender as a function of captured, reproducible EEG signal data generated by the sender (for example, as acquired via an EEG device interface). In some examples the definition of the EEG signature incudes weighting the captured, reproducible EEG signals data, for example, via the ANN model process of 106, FIG. 4. A standard, Fourier transformation or other non-personal weighting or transformation may be also applied to the captured EEG signal data to define the personal EEG signature, and a unique, personal profile or quality of the underlying raw EEG data may be identified to distinguish the personal EEG signature from signatures generated for any other user from their own EEG data.

At 404 the sender encrypts a message together with the sender's captured personal EEG signature using the public key of the receiver.

At 406 the sender sends the encrypted and signed message to the receiver.

At 408 the receiver decrypts the message and sender's captured personal EEG signature using the receiver's private key, and at 410 the receiver will use an ANN weighting model defined according to the present invention (for example, via the process of FIG. 4) to verify that said personal EEG signature belongs to the sender by using the set of publically available, personalized weighting factors of the sender.

In some examples, verification of the sender's captured personal EEG signature at 410 permanently destroys the EEG signature, which enhances security by ensuring that the sender's captured personal EEG signature is not misused or disclosed publicly by the receiver.

FIG. 7 illustrates another, alternative embodiment of the present invention that encrypts information for one person only, wherein only one designated receiver may unlock the message via their own, personal EEG signature. At 502 a sender locks a message via a public key encryption process with the publicly available weighting factors of the designated receiver functioning as a public key; and sends the locked message to the designated receiver at 504. At 506 the designated receiver unlocks the message with the receiver's personal EEG signature by using an ANN model trained by the receiver's personal EEG signature (for example, as trained in generating the receiver's personal EEG signature at 106 of FIG. 4). The decryption at 506 is dependent upon provision of the receiver's unique, personal EEG signature, and thus no other receiver will have an appropriate personal EEG signature that is able to unlock the message.

Thus, aspects of the present invention enable the use of human brain EEG signals as a unique electromagnetic fingerprint, wherein a user may “think” about a password, image, vision or story that is used to securely identify the person and grant access to secure messages, as well as achieve access to other secure items, activities and areas, such as online financial and social media accounts, insurance policies, effecting payment for transportation fares and tolls, etc.

Aspects may be easily and efficiently deployed via wearable EEG sensors that can be integrated into a hat, baseball cap, spectacles and sunglasses, headbands, earphones, hair clips, ear rings, etc., that enable EEG electrodes to be placed upon or close enough to the user's head surface to detect EEG signals, and which may be transferred securely via encrypted Bluetooth®, Wi-Fi or other wireless network connections to a user's smart phone or other portable, programmable device. (BLUETOOTH is a trademark of Bluetooth SIG in the United States or other countries.) Because the EEG signals are very low frequency they can also be modulated onto a higher digital carrier frequency, including via unique ANN model weightings trained for each person, enabling the transfer of captured EEG signals to another computer device in an optimal quality via an encrypted network connection.

Aspects offer obvious advantages over prior art private key and signature systems and methods that rely on the provision of personal identification and passwords for online business such as online shopping and online banking. Such prior art private keys and signatures can be used by other parties, or manipulated. For example, unique biometric fingerprint ID's may be “stolen” (for example, taken from a glass or other surface or medium, re-created or transferred onto a transparent tape and used to gain access to a secure system via a fingerprint scanner. Humans may also intentionally or unintentional divulge passwords and user ID's to others, who may use them to gain unauthorized access to messages, accounts, etc.

In contrast, security is enhanced by aspects of the present invention as signatures and passwords created for a user are not stored within any programmable device, but are instead replicated by the person at will in the form of the procedure that the user will mentally execute to recreate generation of the password via use of the ANN model trained by the user during creation of the password or signature. The imagined password is thereby transformed into something that is unique to the human who is thinking of the password, since the EEG data generated by each person is unique to their individual brain physiology. Disclosure of the mental activity used to generate the password will not disclose the generated password itself, as another person “thinking” of the same password will not generate the same captured EEG signal, as weighted by the user's personal ANN model weightings.

Relative to the prior art, the EEG-based aspects of the present invention provide for enhanced security for the exchange of electronic information, including electronic messages (email, simple message system (SMS), chats, instant messages (IM's), etc.), the exchange of data in public clouds (files, pictures, films and other files), audio communications, video communications, etc. Aspects generate an ultra-secure EEG signature that is used as a signature for the electronic exchange of information and communication, and to dedicate information for one person only.

The terminology used herein is for describing particular aspects only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “include” and “including” when used in this specification specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. Certain examples and elements described in the present specification, including in the claims and as illustrated in the figures, may be distinguished or otherwise identified from others by unique adjectives (e.g. a “first” element distinguished from another “second” or “third” of a plurality of elements, a “primary” distinguished from a “secondary” one or “another” item, etc.) Such identifying adjectives are generally used to reduce confusion or uncertainty, and are not to be construed to limit the claims to any specific illustrated element or embodiment, or to imply any precedence, ordering or ranking of any claim elements, limitations or process steps.

The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
